Chicago-Latrobe 44919 Cobalt Jobber Drill Bit

The Chicago-Latrobe 44919 is a 19/64 in cobalt jobber drill bit designed for drilling hard metals. Its 135 degree split point reduces walking and starts holes accurately. The TiAlN coating adds wear resistance and extends tool life in demanding applications. This bit is built for professional and heavy-duty use.

Suited for machinists drilling stainless steel

This drill bit suits machinists and maintenance technicians who need reliable performance in tough alloys. The cobalt construction and split point geometry handle high heat and hard materials effectively. Buyers who want a bit for wood, plastic or soft aluminium should look at something else. It is not intended for coolant-through operations or non-metallic work.

135 degree split point with TiAlN coating

The 135 degree split point is the specification that decides if this bit matches the job. It centres quickly without a centre punch and reduces thrust in hard steel. The TiAlN surface treatment further improves hardness and heat resistance. Decimal equivalent 0.2969 in confirms the exact size for precision setups.

Questions about this item

How much heat does the 135-degree split point generate when drilling cobalt steel all day?

The 135-degree split point on this cobalt jobber bit reduces thrust and heat buildup during extended drilling in hard materials.

What shank size must my drill chuck accept for the 19/64-inch bit to fit?

The 19/64-inch jobber drill has a straight shank that fits any standard three-jaw chuck capable of holding 0.2969-inch diameter.

Will the TiAlN coating on this 44919 bit wear faster on older cast-iron workpieces?

The TiAlN coating resists wear and oxidation, so it maintains cutting performance on abrasive cast iron as well as on newer alloys.
